[Therion] Joining scraps and PDF layouts

Hello, I am busy completing a survey of a cave and I am running into two problems with the final PDF First problem. There are water areas that cross over two scraps and the water is coloured blue. In the PDF file, the line where the two scraps join show a thin white line. The kml and loch files don't show any split between the joint scraps. Any idea how to fix this? Second problem. I would like to display the cave name, scalebar etc in one area of the PDF and have my legend in a seperate area of the PDF, but I can't figure out how to do this. Any help will be much appreciated! Thanks in advance, Steven
